Abstract: In an information processor, a situation and operation storage section stores situation information, acquired by a situation acquiring section, about a situation in which an operation has been performed and operation information, received from an operation section, about the operation in an associated manner. A situation comparing section compares a current situation information piece with situation information pieces stored in the situation operation storage section. Based on situation information pieces stored in hierarchical structure in a situation hierarchy storage section, a broader concept common to two situation information pieces compared by the situation comparing section is searched for.

Abstract: Method and apparatus are provided for editing input information. Input information is received from an input means (1) from which a keyword is selected for editing purposes. A low level record is located in a memory (5) which has the keyword of the input information stored therein. The low level record having the keyword stored therein is accessed to determine the location in the memory of higher level records and information types of the higher level records. The higher level records having stored therein explanatory information for the keyword in accordance with the information types of the higher level records. The higher level records are of a plurality of information types for presenting different types of explanatory information regarding the keyword, such as a definition of the keyword, a synonym for the keyword, an example usage of the keyword, etc.

Abstract: A system for creating an index of textual data stores textual data in memory, and a text analyzing module analyzes the textual data and divides it into a plurality of meaningful strings of characters, punctuation marks, symbols, control codes, etc. A dictionary stores sets of specialized words particular to a field of knowledge related to the textual data in a particular language. An entry selecting module selects as index entries only those strings which match one of those specialized words and notes the location(s) of each occurrence each index entry in the text. A printer outputs the selected index entries together with their occurrence positions. Each entry of the dictionary in the specialized field includes information concerning inflections and variants of that entry. The index is quickly and accurately generated by selecting index entries using a specialized dictionary relevant to a particular, specialized field.

Abstract: A text processing system for example a word processor includes a storage unit with two storage devices. The first storage device can store at least two character strings in an arbitrary order. The second storage device can store at least one index. Each stored index designates a predetermined one of the character strings. The indexes stored are in a predetermined order.

Abstract: A computer, in particular a word processor, is structured to enter and store Japanese symbols and character strings. The word processor includes an operator defined dictionary. To enter the new words in particular Japanese words into the operator defined dictionary, reference familiar to the operator are displayed. The reference words which are similar in linguistic form to the new words, have parts of speech which are prestored in a dictionary of the word processor. The operator obtains the parts of speech of the reference words which are comparable to the new words. Thereafter, the new words with identified parts of speech in proper form are entered into the operator defined dictionary.
